Recently, news of Ocean's vocal troubles made headlines when he walked off a stage at Norway's Oye Festival suddenly after performing just four songs. Apparently he "got sick and lost his voice," which a festival representative revealed to the crowd.

The "Super Rich Kids" singer debuted his solo album Channel Orange in July. He performed several shows in support of the LP across the U.S. He was set to continue doing so with the upcoming Coldplay world tour.
